Our eyes today constitute one of the most complex organs in our body. How our eyes capture light and transform it into crystal-clear images has become one of the most controversial topics today because no one has ever fully studied and studied the eye. Therefore, my question was: "How do red eyes appear and how do they apply to the two main factions of eye structure?" » Through extensive preliminary research, I learned a lot about the structure of the eyes and how to perceive vision from another point of view. The general eye can be classified into two main constructs: the simple eye and the compound eye. The simple eye, the one we have, looks mostly like this: In this diagram above, the major light-sensitive organs are labeled. When light enters the eye, it must first pass through the cornea and pupil, which is like a window through which light is filtered and floods. Then the light is filtered again by two walls called irises, which detect color and send these messages to the brain. The light continues to pass until it reaches the retina or the lining at the back of the eye, which acts as a sort of screen on which to place the image. Here, nerve sensors take the image in the form of impulses and send it to the brain. As for my main question, I would like to talk about red eyes and eye shine in general. Red eye appears in flash photographs taken in dimly lit areas, such as an aquarium or movie theater. This happens when the bright light from flash photographs illuminates our pupils like light pouring into a room, allowing us to look inside. The red color comes from blood vessels located inside our pupil. For vertebrates such as dogs, cats, bats and owls, a mirror-like gland called the tapetum lucidum covers the retina, which reflects...... middle of paper...... the pupil hole. By studying a piece of rented calcite, I was able to discover how the structure of the compound eye could not function and how it could not reflect light at a direct angle. In conclusion, my conclusion is that red eye only applies to eye structures with reflective surfaces, such as the single eye. Compound eye structures are conical and have a layer of graphite, unable to reflect light but must absorb only direct light to produce a certain image. Our lives sometimes depend on our eyes. Consider covering your eyes and crossing a busy street. By studying red eye and how it applies to our lives today, we can use it to our full advantage. For example, ophthalmologists shine bright lights into our eyes to see inside them without harming us. This type of research may lead to major improvements in laser surgery and safer eye habits..
